“…An excess of Pb results in n‐type conductivity in PbS, whereas an excess of S results in p‐type conductivity . The size dependence of a bandgap in semiconductor nanoparticles is well known, and modifying their size facilitates the tunability of their optical properties . Metal sulfides are important materials because of their wide‐ranging applications in optoelectronics and catalysis.…”

A highly efficient rotating packed bed photocatalytic reactor based on Fe3O4@PbS@Ni2P composite for the degradation of fenpyroximate (FP) as an acaricide in agriculture is described. The visible‐light‐driven photocatalyst was characterized using various techniques. The interaction of operational parameters consisting of rotational speed (400–1200 rpm), photocatalyst dosage (0.20–0.40 g l−1), solution flow rate (0.10–0.50 l min−1), aeration rate (15–35 l min−1), FP initial concentration (5–45 mg l−1), pH (2–10) and irradiation time (20–100 min) for FP degradation was examined via central composite design under response surface methodology. Accordingly, under the suggested optimum conditions, namely rotational speed of 950 rpm, Fe3O4@PbS@Ni2P dosage of 0.30 g l−1, solution flow rate of 0.30 l min−1, aeration rate of 25 l min−1, pH of 6.0 and irradiation time of 85 min, more than 99% of 45 mg l−1 FP was degraded. The Langmuir–Hinshelwood kinetic model was the best equation for the description of the experimental data. According to the rate constant, the contribution of photocatalytic degradation, adsorption and photolysis to the reduction of FP concentration and, subsequently, the efficiency of water treatment were studied.

“…Interest in the preparation of lead sulphide semiconductor nanoparticles are due to their size-dependent properties [1] and potential applications as optical sensors [2], photodetectors [3,4], photocatalysts [5,6] and solar cells [7]. PbS is IV-VI semiconductor with a large excitonic Bohr radius of 18 nm, high dielectric constant [8][9][10], and small direct bandgap (0.41 eV) that can be tuned from 0.3 to 5.2 eV for specific application [11]. Several methods have been used to prepare PbS nanoparticles such as thermal decomposition [12], chemical bath deposition [13], irradiation by gamma rays [14], mechanochemical [8], microwave [15], singlesource precursor [16], colloidal route [17] and sonochemical method [18].…”

We report the synthesis and morphological studies of lead sulphide nanoparticles prepared from lead(II) complexes of morpholine dithiocarbamate (PbS1), thiomorpholine dithiocarbamate (PbS2), and N-(2-hydroxyethyl)phenyl dithiocarbamate (PbS3). Powder X-ray diffraction patterns (p-XRD) of the PbS nanoparticles are indexed to face-centered cubic phase of PbS. High-resolution transmission electron microscopy (HRTEM) micrograph revealed quasi-spherical PbS nanoparticles with particle size in the range 13.86-36.06 nm while scanning electron microscopy (SEM) revealed flaky/spherical/rough surface morphology. Photocatalytic degradation of methylene blue dye by the PbS nanoparticles showed degradation efficiency of 72.6 % for PbS1, 75.9 % for PbS2, and 47.4 % for PbS3. The photodegradation efficiency shows a correlation between efficiency and morphological properties. Total organic content removal by PbS2 is 69.5 % while that of PbS1 is 64.2 % and PbS3 is 40.1 %. The as-prepared PbS nanoparticles exhibited remarkable photostability in the recyclability studies.

ZnO/FeS tubular nanocomposite was successfully synthesized by a facile two‐step chemical route. The as‐obtained composite was composed of the hexagonal ZnO tubes with a mean diameter of 150 nm and cubic FeS nanosheets with a thickness of 35 nm, and FeS nanosheets grew epitaxially on the outside surface of ZnO tubular microstructures. Furthermore during the process of FeS nanosheets coating on the ZnO needles, the acid etching leads to the formation of ZnO/FeS tubular structure. In addition, the as‐prepared ZnO/FeS tubular nanocomposite exhibited the enhanced optical properties and absorption degradation activity. After 30 min, the absorption degradation ratios of the as‐prepared ZnO/FeS tubular nanocomposite for some organic dyes can improve greatly [Methylene blue, MB (82.4 %); Rhodamine B, RhB (94.5 %); Pyronine B, PB (86.6 %) and Methyl orange, MO (78.5 %)] when compared to the individual ZnO needles.
